Dysfunction, Left Ventricular
Conditions
Brief summary
The aim of this study is to evaluate, in an intensive care unit, the reproducibility between two non-cardiologists operators and a cardiologist expert in echocardiogram, of the Simpson method and of the calculation of GLS for the evaluation of the systolic function of the left ventricle in critically ill patients intubated and ventilated.
Interventions
Cardiac echocardiography to determin the left ventricular ejection fraction by the biplane modified Simpson rule and by the calculation of the Strain Longitudinal Global by 2-D speckle tracking strain echocardiography
